Cottage Industries 1/72 Hunley

Hey-

  I've been working on Cottage Industries 1/72 CSS Hunley.  It's a terrific little kit that goes together very nicely.  It's complete and I just need to paint it.  But before I paint, I was playing around with display bases and thought I would get some opinions on what I came up with.  It's a simple wood base with a seabed and a acrylic rod to hold up the Hunley.  It's an air hardening clay sprinkled with sand and painted.  Any comments or suggestions?

Thanks,

Phil
